Epic is a great tub and was one of two I debated heavily on before ultimately choosing an Artesian Grand Bahama Elite. The HK60 tower jets were awesome to be in front of (floating from the force) or sitting across from. For me, the HK40 in the chair with air ON would fill my shorts and lift me out. So, a snug bottom suit or none at all seemed the only way to go. Wife in bikini bottom didn't experience that. Give it a wet test.
Not sure of the price difference but it seems for such a long term investment, you're better off buying more tub than you think. You'll lose big time on depreciation so if you change your mind in a few years it'll cost you more.
