you want the f1 for rough ground mate and thats pushing it a bit i had one and sold it on as it was not man enough really,the f2 is more of a match type rod but very nice all the same hope this helps,lee.
its 14 foot and more of a match rod clean to medum ground
if you want a bit more get the V-MAX F-1 as this has a bit more poke.
the best Zziplex i have used on rough ground is the XTR sport this is a skull drager
I had one. They do vary in feel. Mine was heavily built with loads of underwhipping and high build and felt sluggish compared to other F2s I've tried since. I agree that its more of a clean ground rod but the tip was ok in fast tides.
Secondhand ones are regularly seen on ebay!
