I hadn't kept up with this thread since posting at the beginning. Thx for the pay on the back PF! I got my roller on eBay. £11 including postage, its from an on line Physio store. Happy to post a link later if anyone is interested.
Don't over do the rolling. Little and often works for me. You can also use it on calfs, glutes, hams, quads. Although any one watching you roll your quads might think you are trying to hump the carpet! Lol.
