Well I'm still new to riding in any sort of group let alone a paceline. The folks I've been lucky enough to fall in with are a convivial bunch of several dozen mostly DF riders of varying abilities. I say mostly DF riders since there are several 'bent riders who preceded me, including our own castlerobber. So they're used to the occasional recumbent even though often it's just me on a given day. I've worked my way up to the 'faster pack' but am acutely aware of pedlpadl's concerns since I feel the same way: being behind me doesn't offer much of a draft, and I hate to just stay in the back being a wheel-suck, even though this group is very gracious about allowing just that. So what I usually do is ride either too far back to really be drafting, or off to the side so I can sort of move forward and back depending on terrain. On the V I rarely have trouble staying up on climbs but then I hate being in the line and having to constantly scrub speed on the downhills. So I drift along to the left, and on downhills just coast, sometimes passsing nearly the whole line, then continue coasting on the flat or next uphill till I'm back in the back and off to the side, and resume pedaling, having enjoyed a nice break
That way I don't feel like a parasite, and feel pretty good knowing that my solo pace could be the same even without the pace line. The good thing about the group is it keeps me from getting lazy like I might do on my own and gives me good motivation to suck it up and keep up even without much* drafting.
If I'm lucky maybe I'll find a smaller rider to team up with like ratz and Lief talked about earlier. Would love to take my turn on pulls and feel like I'm actually contributing. That would be cool.
*confession: I do occasionally slip into the line and draft on the flats. Just for practice, of course
