poulton is a nice club (div 1 is the league below Wepl glos that cirencester are in), but their 2nds are in div 7 - which is only 2/3 league off the bottom of the pryamid, from what you say i think cirencester might be best, ciren 1's are a decent side in tier 3 - wepl glos and there 2nds are in div 5 there is not a huge difference in quality between the weak sides in div 3 down to div 6 (as the GCB messed up the pryamid when they intergrated the 2nd/3rd/4th teams into the Glos County League
cirencester is also a nice place to play and the club is very friendly and forward moving
