Here's my thoughts for what they are worth. I suggest getting the 1/4" in both Hot Rolled and Cold Rolled if possible. They will give the most variety, especially if you are able to get in it longer sticks and cut it down yourself. You might also want to look into getting 6" Timber Ties as well.
As for wraps the IM cordura wraps take some breaking in and have a learning curve, so lots of chalk. I would also suggest reaching out to Devin Hoover (instagram @eatchalkgetbig) or Chris Rider (instagram @hairculese), for leather/suede wraps. The leather/suede will be easier to work with while learning.
Hope this helps you with your journey.
