If I were you I'd give the husky 555 a hard look.
Based on what you're saying you don't really need a 70cc saw or larger.
With something like a 555, 562 or stihl 362 you could reasonably run an 18-20" bar very well in Hardwoods; such bars would enable you to cut about 32-36" wood at maximum.
A 550 or other 50 cc saw could well be adequate but if you're comfortable limbing out the smaller stuff with your 335 then this reduces some of the need for the saw to have really good handling for limbing.
Do yourself a favor though and sort out the brake on your top handled saw.
I second the 555..i ran one for a few hours last weekend and was impressed !
