when you say slipper clutch, do you mean one that limits compression lockups on downshift? i have heard that the cbr600f4/5 is a bike (not gimmick) that makes up for weak technique, would you consider one of them?
CBR600F4 & F4i are great bikes if you want something that's just going to do what it's told. They're so well refined they're almost boring to ride... well that's just my opinion. They easily handle commuting, twisty rides, and even track days. AFAIK there was no CBR600F5 as Honda ditched the CBR600F's in favour of the RR's.
the reasonn your bike feels like its sliding the rear it's because you are accelerating mid corner , once you commit to a corner don't whack on the throttle but rather roll it on as youre coming out of the corner its the rear tyre that steers the bike not the font. the front wheel only counter steers the bike (sets up your lean angle) try it push left to go right and push right to go left
hold on a sec i dont know how this got so off topic all i asked was do any of the other bikes on my list come with a slipper i never said that because the new yzf's have them that ill be buying one for shore, does give it more points on my list but if another bike that doesnt have a slipper takes coners better and has the right power to suit my riding needs then more then likely i wont have a slipper
