Thanks guys, it's refreshing to get an honest opinion on things that is not polluted by "mine is bigger than yours" and other personal insults, especially from two opposing sides of this.

Couple points I would want to make that make me lean towards 300:

•I already have stock 250 and planning to build "Tuned" 250 some day to compete in P89 class (Production pre-'89),
this will be a an independent project, not expecting to complete this any time soon as I need to clear up my storage of all the old junk, hopefully sell some of it so I can free up some funds

•this bike will need pipes either way as all I have at the moment is MC21 frame MC28 ProArm and R6K engine (also 21 subframe, Radiator, some bodywork, yokes... etc)

•always likes 4 stroke twins, love the low end power, also like having couple completely different bikes I can throw a leg over on any given day depending how I feel.

My current line up is the recently finished R5K, RG500, Tuono and KTM LC4, that's what's on the road and ready to ride, another half dozen projects like VF1000R (x2) RD400 (x2 and hopefully both sold) Yamaha AT1 125 cc Enduro, Hawk GT (Bros in UK) it was my old race bike with Ducati inverted front end, 700 big bore, cams, Ohlins etc.. that one been shelved for 10+ years since I married and quit racing, some day it will be back on the street. Add 10 or so scooters and I got my plate more than full, everything always needs work and money so got to pick the projects wisely and sell some of the toys that I no longer use like my GS150 and P200 and RD's and VFR's
