What are the options available for flat concave popsicle decks? I skated a Brandon Westgate element that was really nice in that regard but I don't really like element as a brand. What are my other options?
Was it a PS Stix or a BBS Element deck?
Similar boards from PS Stix are more on the flat side, as are some from BBS too, but it will depend on the mold, as both woodshops have more mellow and steeper concaves in their ranges.
There are also quite a few different woodshops that have very flat concave and kicks, again dependent on which mold is being used, more so than specific brand, but I am sure people would have their own personal preference on boards like that too.
