Hello,
From a casting perspective, I guess the V2 turns over a little bit easier for me but I didn't really have trouble with the original design. Frankly that's about all I've noticed. The other items are more cosmetic than anything.
In a nutshell:
- slight redesign of the taper
- line ID added to the line
- new color
I'd say buy the old model if you can find one for cheap or on clearance, slightly used, etc. Otherwise buy the new model. Can't go wrong in my book...
