That is true, but will you really need that extra strength? Going 200mph in a race car sure, but cruising around in the woods and taking a roll? Im not rich, that DOM is twice the cost.
You should just stop talking. Nobody cares if you wanna build a cage out of cheap shitty material, but you shouldnt influence others to do the same. Thats like sayin a 5 point harness is overkill, stock belts are plenty stong.... 38in swampers are too expensive, run 27in street tires instead, theyre half the price.
Any tube that is ever intended to contact rock in any way should be DOM.
