Here's my current rotation of gels:

Aura Hypoallergenic
Angell
Abba Weightless

My three A gels. Abba by itself is too much like glue for my hair: no matter how wet my hair is when I put it in, how careful I am at using on a bit, etc. Angell by itself gives me great clumps but not enough hold. Abba + Angell has so far been the best of both worlds: clumps and hold. I am having much better luck with this combo in the hot weather. Aura does OK by itself, and I do add a dab of Abba on occasion as well. Aura is not anything super special, but it's good for mixing with other gels or for a lazy weekend day when I'm just looking for no-frills, quickly styled hair.

Aquage Defining Gel

OK, another A gel. I actually think I like this one the best. Nice easy-to-spread consistency, good hold without being super strong or ultra crunchy, nice clumps, nice shine. It's not super CG friendly, so I try to rotate it with my other gels. I do poo (currently with a mild sulfate) so I'm obviously not strict CG, but I do like to avoid or at least forestall buildup as much as possible.

B&A

If I have one gel I use more than any others, this is it. Great all-around gel. Does pretty much everything for my hair: hold, clumps, curl enhacing, shine, etc. A bit pricey but does last for a very, very long time. Between this and the Aquage, I could be happy (if only the PJ in me would accept it! )

HE HDG

Not as big a fan as I was a month or two ago, but still good for what it does. Gives me a less curly look than the others I've mentioned, but nice for a change every now and then.
