All reel styles require some learning and practice.

I use both stainless and plastic. I find stainless less fiddly but both types are very usable.

The big reason I use plastic is because I use a JOBO processor for C41 and WD2D+. When developing with DD-X in hand tanks stainless is by far my preference.

Different brands within each style can be better or worse. The Hewes reels http://www.bhphotovideo.com/c/buy/De...8/N/4077265214 have a great reputation. Mine work great.

In plastic I like JOBO's but they don't fit in my stainless tanks.
