I'm looking at getting a portable basket and I'm know people on here will have had experience with more than one and can hopefully lead me in the best direction. So let me know what basket you prefer and why.
define what you feel is portable. Are you looking for fold up and carry, or a basket that can be broken down and re-assembled. There are a few different kinds of portable baskets, it just depends what you are looking for.
If you fashion some extra chains (which is really easy and costs ~ $15) the Skillshot is a really nice catching target and has a smaller window which is nice for practice.
I've traded most of my foldups in for the simple Innova Traveler baskets because you can't beat the lightweight and packability of those things. You also never have spit-outs because of the fabric/chain combination although many 'bad' putts tend to go in because of the overly generous 'basket' portion.
