I climbed maybe 10 or 12 years on steel Buckinghams, another 15 or so on Bashlin Alcoas, and 5 or 6 on Gecko carbon fiber with west coast straight tree gaffs (not those damned Euro bird's foot trash

). Now, after retirement (which required that I return the CF Geckos to Uncle Sam

), I am using Buckingham titaniums. And I spur climbed a lot, and a lot of big PNW conifers. I am not shy on calling myself well-qualified to rate them all

. Though in truth, if you're climbing east coast/midwest hardwoods, then probably someone else will perhaps be a better source for feedback

.
So...I liked the Bashlins a lot, worth what they cost and the savings of a couple of pounds lighter that the steel Bucks helped me in that much of my work required cross-country hikes to the trees. I'd happily recommend them to anyone. Better than the steel Bucks, but only in the pack carry category, really...though after a long day on gaffs, the lighter weight of the Bashlins was noticeable to me.
The CF Geckos were unbelievable, I laughed out loud whenever I picked one up, so light as to be magical. I loved them, and wish I still had them...but the price is steep, eh? If I had the money and it wasn't going to take food from my family's table, I'd go that way. You never even notice they are there.
But if the price was a stumbling block for me, I'd go with the Buckingham T-2 spurs. Damn light, great gaff profile, and not so dear as the CF Geckos.
