Andrew - Its the 115. I'm 190lbs. Honestly I don't know what Quatro says for the sail range - I'm sailing 6.3 to 5.0 on it. Could easily sail a bigger sail on it if I had one. The board is a nice "all around" board for waves, B&J, etc. To be honest, this was to replace an old (and I mean OLD) RRD TwiTip 110 that I've been using as my light air board - and thats a hard board to replace in terms of its planing ability, pop, upwind power, etc. I'm still dialing in the 115 but she's gonna be a keeper. Fins are a big issue with it - not a fan of the stock fin that they provide with it. I'm testing out a whole slew of fins on it, super fond of the Black Project Kraken that I'm running on it now. Its super fun on the lake - lots of power for onshore where upwind ability translates to power for backside hits, but still goes rail to rail quickly and carries lots of energy for onshore "round house" style frontside wavesailing. Hope this helps!
