In reply to Matt Buchanan:
My 45 is mostly wooden screw ons plus a few resin holds which are a mixture of screw on and bolt on.
If I was to start again from scratch, I might not bother with any tnuts.
There are so many good wooden hold makers, you can get whatever shapes and sizes holds you want. I have a mixture of beastmaker, hardwood, silly goat, strongholds and Taylormade. They are all good and I think having the variety is helpful.
The only 2 disadvantages of going fully wooden:
- consider the conditions where your board is going to be. Mine is indoors so I don't have any issues. Some outdoors/shed/garage/cellar boards can suffer badly from condensation if you don't get the ventilation right. Some woods are worse than others when condensed. I've heard oak can be particularly bad for it.
- If I'm not able to climb outdoors or on resin for a while, my skin goes very soft. Wood is great for not wearing out your skin when it is combined with rock/resin but it doesn't do much to condition your skin. Not an issue if you always have access to rock/resin. But if not, I'd consider adding some resin holds. These can be screw on or bolt on. Retired holds from a wall are ideal to avoid the rough new hold feel.
