Piet,<br>Great to see you here.<br>I have been out of touch with you for a while. You are not forgotten<br>I love the Thinsulate version of the poncho liner so much and also, it packs a tad bit smaller than issued ones. I even bought a second one. I already own the issue onese and I think that weight for weight, the Thinsulate versions are warmer. When its hot, I lay the P.liner as a ground sheet in the tent and makes a smooth silky , and cushoned surface to rest on.<br>Hope that helps. Dont know much about the converter kits but Ranger Rick swears by it :-)<br>Warmest wishes,<br>Oliver
