comparing new xfactor and stealth

[icelogger]

This question is for you guys that have tried them both. I saw the big sale coming up and perhaps I may buy one.

What are the big differences with xfactor and stealth, pros and cons, such as built in bait tank location, ease of moving around reaching for different hatches, stability, performance, differences between the 12 and 14, any other big differences?..... I've only read the
The manufactures descriptions.

Also, for those of you who have paddled hobies, a question about these drive fins. Do they really make kayak fishing that much better, or are they just an added bonus to kayak fishing? Why are they so great compared to malibu?

Thanks
