wow, you have been sooooooooooooo helpful. i feel stupid for not looking at the place's original temps, WHERE THEY LIVE AND SURVIVE!Temps of low 60°s are too low. You want to be low to mid 70°s for albopilosum.
Check the natural temps in the region where your species of interest live. Your 'rose haired' is from Chile, whilst B.albopilosum is from honduras, nicaragua and northern costa rica. These regions have a very different climate to Chile.
On this wiki page is climate data suitable for B.albopilosum

But, dont go near the extreeme temps listed, especially avoid the highs. Why? These tarantulas live in burrows underground while the temps are airtemps. The burrows buffer the temps (and humidity) to maintain a cooler burrow than airtemp (dark and cool deep inside), and actually the burrows also retain warmth above the coolest airtemps (the ground retains warmth from sun better than air). So, when temps drop everyday at nighttime, the ground stays warm well into the night when the air gets cold quickly....
So.. for this species, keeping an average of about mid 70°s is about right, warming upto high 70°s/lowest 80°s in the summer. TMRKD, i'd say mid 80°s is going too hot, whilst the low 60°s of NickC4 is much too low. That could be harmful to albopilosum, particularly if over long periods, with low temps the spider will become slow and unresponsive, and stop feeding. Death is likely.

now compare that to the one from La Ceiba for albopilosum. Much lower temperatures in Valparasio, Chile - so mid 60°s, say average 65°s is even quite ideal for such species, whilst higher is less desirable. But, B.albopilosum need it to be much warmer, as above.
ps. If for Megaphobema you also mean the species mesomelas and peterklaasi, those will happily tolerate lows towards 55°C, whilst mid 60°s or lower are actually ideal, upto a max of 70°s
I have to disagree with what you've said my room is in the 60s right now and my Ts are doing just fine. Tarantulas are very adaptable creatures so *hypothetically* you can take them to right above freezing and they will live just really slowly. So they actually will take better to cold spells rather than heat.Temps of low 60°s are too low. You want to be low to mid 70°s for albopilosum.
Really? Is your room low 60's?I have to disagree with what you've said my room is in the 60s right now and my Ts are doing just fine.

Good luck getting one to survive a molt at those temps.Tarantulas are very adaptable creatures so *hypothetically* you can take them to right above freezing and they will live just really slowly. So they actually will take better to cold spells rather than heat.
:sarcasm: Cold makes things harden up right?Good luck getting one to survive a molt at those temps.

In the 60s and 70s yeah I don't bump anything up, Sean was talking about towards freezing. Ts are more durable than you think.Yeah, I picked up that at the library when I was first considering a T. It helped me a ton. So your t's are fine at those temps? And do you kick up the temp for molts? Sorry to ask so many questions but I don't want to get my second T only to kill it.
My turn to chime in.Good luck getting one to survive a molt at those temps.

just go for it... hell, get 2 or 3. B. albopilosum is actually a really cool t/sling. i got mine as a freebie when i bought my 1st P. regalis sling. this curly is a real aggressive eater, and is always in the open. in 8 months that ive had it, its grown from .25" to around 3.5" to 4". pretty fast for a brachy. ******to answer your ? about temps.... i keep mine in the mid to high 70s (maybe let it cool a bit at night) and, aside from the waterdish, no additional humidity other than like a once every 10 day LIGHT misting . between the temps and the powerfeeding (this one gets fed alot) thats prob why its gettin so big so fastIt seems like there's only slings on most sites and dealers though....
