It's only like $64 shipped for the Fenix L2D Q5 and the TwoFish bike mount after using the cpf8 discount at
www.4sevens.com , and if you already have a mount or think you can make your own... it'd only be like $57 for the light alone.
That's not bad at all. And considering it's a bright white light that doesn't dim because it's regulated, lasts for hours off of 2-AAs, is waterproof, very durable, super compact (I think I'm gonna carry it with me always when I'm not riding), and makes a nice weapon to boot... I don't see the problem.
I loved the Coast P7 I bought, but I left it at a friend's house, who ended up having problems with her roommate, so her roommate broke the lease and started packing her stuff and ended up taking my flashlight with her. $95 down the drain!! One of the biggest mistakes of my life. Oh well, at least I'll be trying the Fenix out in a couple days, and I'll be able to see which light really is better for biking.
