I've been "poncing" mats all year and through trying them all + talking to the people who own/use them I've ordered an A.I.M mat! Bigger, comfier & much more durable than any of the others ive tried. If your only an "occasional" hft'er. The others that concertia are fine. Roll up ones are ok if shooting in one place, not 30 different ones! ;-)
If you can find a 2nd hand aim mat buy it but folk don't sell em as I've been looking!
