which helmets are you guys using?

[nick crisp]

Just bought an HJC IS-17, black. Judging by short ride home from work today in hot sunshine, the vents work well, really noticed the difference. Drop down dark visor - first one of these I've had. Seems to fit nicely with no uncomfortable tight spots. Retails at about £140 - brand new at £76! That'll do me...
Nice to retire cheap £45 Box that I only really bought to pick up the bike when I bought it. Will do for a spare. Was going to wait for next lot of HJC RPHA10 Carbons to come in, but going to Wales next week, so needed something decent sooner. Will let you all know what I think of The IS-17 after a bit more intensive use.

Nearly forgot this. OK, fits real well, snug but not uncomfortable. Still impressed with the vents after having so many lids where I didn't know if they were open or closed for all the effect I got. Nice to have the drop down tint visor, obviously that's been a real bonus lately, but I think a decent pair of shades keeps the wind out of my eyes better. However, unintentionally, it has it's own way of coping with this; The visor ratchet is a bit looser than it should be, and I was thinking about sorting this when I got back to work (replacement visor and/or base plates), but actually, the wind tends to blow the visor shut just as it gets a bit too much! So, a happy accident    Light and aerodynamic enough to not really notice the weight (though carbon, say 1250/1300g, better in this regard). This helmet, Med., marked 1500g. With hot, sweaty couple of days in Wales recently, thankful that cheek pads and crown liner removable and washable! Oh, and by the way, watch out for weight claims, even as marked on helmets - manufacturers often say a certain weight, and often this will be marked as the same on all sizes of a particular helmet, but eg, HJC generally use three shell sizes (XS/S, M/L, L/XL), and of course, the larger ones weigh more! (Although to be fair, it may not be a really noticeable difference). Liner material soft and comfy, not at all abrasive, Double-D-ring strap (my personal preference as easy to adjust on the move) with press stud fastening for excess strap length. Chin curtain fits nicely and does a good job of keeping unwanted breezes from coming in from unwanted direction (not a problem lately, but is easily removable). Visor removal & refitting is quick & easy. Pinlock insert supplied. That's about it, so I'd say I'm pretty happy with it. If it's the right shape for you, I'd recommend the IS-17.
