Nalu once bubbled...
Thanks that really helps a lot!! On their website it says a size 8 is for someone weighing 120lbs so between the two of your answers it seems like they run bigger than they list them which is great. What do you think about your core warmer? Does it feel very bulky? Also, was the 10 much longer than the 8? Thanks
No problemo - anyway I can help someone avoid the wetsuit plight I had!
SIZE - I was on the fence between the 8 and the 10. Once I finish losing my college weight I will probably get it back down to about 150 lbs... that's why I leaned towards the smaller size. I also have the build of an out-of-season athlete (unfortuately I have that build while in-season :-( ) so I might be a bit denser than what they have the sizing charts caculated for. I also choose to run the risk of stretching the suit a little thinner to keep from getting gaps... it's a personal choice.
If you can't try one on at an LDS, I would suggest trying to order from a place that has a non-used return policy. It might be worth paying a few more bucks to be able to exchange it if you get it in the mail and it's just not the right size.
LENGTH - I didn't notice much of a length difference between the 8 and 10 full length suit... but check the specs from the manufacturer. I have a rather short torso, so length never seems to be a big problem for me.
FLEXIBILITY - I have more flexibility in my 7/5 one piece hyperstretch than I do in a 3/2 regular one-piece neoprene suit. I can reach my first stage, even with my hood on (hyperstretch also... and well worth it on the hood). After having this suit I will be hard pressed to go back to 2-piece neoprenes, or even one piece standard neoprene. The core warmer does reduce flexibility somewhat... but still rivals the flexibility of that 3/2 suit... only now it's 12 mm of neoprene in places. If you're really concerned about flexibility, get the hyperstretch core warmer... it might cost you an extra 30 bucks.
CORE WARMER - I don't find the core warmer bulky at all; it's a tank-top style top attached to "shorts"; entry is by velco on one shoulder. Once you have the one-piece suit on, the regular neoprene suit just slides right over (okay, with only a little coaxing). So I didn't feel the need to get the hyperstretch core warmer... especially since the regular neoprene might be a tad warmer for the thickness. Just remeber if you get a regular core warmer, go a size larger than the one-piece.
PRICE - I bought from a rather pricey LDS, b/c they were the only local henderson dealer and they had a great return policy (ie allow me to exchange sizes on an already-dived suit). I believe I paid about $345 for the 7/5 one-piece and just over $100 for the regular neo 5mm core warmer, 7mm hyperstretch hood was roughly $45... all this before tax. Part of your economic decision will need to be weither it is cheaper to get a hyperstretch or order a custom. I know very little about customs, so I can't help you there.
Good luck!
