TBH i tend not to ride in the wet if i can help it, done my share of all that however i lean (no pun intended) toward the battlax. i have always found them never to give me any brown underwear moments when conering and excellent wear when on straight runs due to the dual compound.
tyres are and will always be a personal choice unfortunately they are not something you can have on free trial and swap them if not happy.
if you have tried many tyres and found them all a bit off in the wet maybe its something to do with the bike, like wheels out of alignment which could only show up in the wet as it would allow the tyres to do their own thing on a slippery surface,
i never trust the marks on the swingarm to set anything they are mostly always "out"
i have avons shod at the mo and not to keen they feel a bit vague and unassuring thru bends, could be i ride a heavy ol' girl.. but will be changing them next year for battlax's
