Ya should try using a little small one sometime.
I got this tiny 3/4" slide that fits over my 3rd finger.
You can leave it in place and still play most chords, but you can use it anytime you want just to add a little extra flavor to your playing.
Plus it suprises the hell outa people... you're playing and have this silver thing on your finger that looks like a big ring. Everybody's wondering what the hell that thing is... suddenly during one solo, you just use it to hit a high note on the 32nd fret right over the pickup. Or use it to slide a chord down really slowly.
You can keep it handy by duct taping a piece of coathanger to your mic stand.
When you're not using it, you just hold your finger over the coathanger and let is slide off.
When you want to use it again, just stick your finger in and it fits back in place.
