(possibly annoying)designer steel query
I'm a heavy/pleasantly plump/portly/fatback/rolly-polly type of gent. However ya wanna call it, the scale says I weigh about 250lbs. I'm looking into getting a custom frame built; a 26"wheeled hardtail, for trail-usage, designed around a 5" travel fork. I'm about 5'11" and typically ride a 18" frame when such sized frames are available. The folks I'm lookin' at work with Reynolds tubesets, and I'm wondering if I ought to go with the 725 or the 853.
Now, before anyone says "Dude, did you even search? We hate it when ppl ask questions similar to other questions!", I'll tell you that I have searched. I've researched the tubesets. I'm aware that people will tell me the relative tensile strengths of the 2 tubesets. I have already seen countless documents that list the properties of 725 and 853 in numerical terms that make little difference to me. I know that at least 6 of you will type "*you*'d never know the difference!". I realize that some clever person will say "all steel weighs the same". Someone else will toss in the red herring, with some reference to true temper S3 or something. Many of you will hate me for resurrecting an old topic, and I apologize. For some people, maybe online forums like this are going to generate more frustration than they do enjoyment...
Anyway, I'm really sorry for posting a question on the board, but I'll try to keep it simple and I'm hoping to insert a novel topic to the discussion, which is myself and my selfish desires as a cyclist. Y'all have yet to hash that one out on this boards. I'm looking more for "pimpness" than I am a specific weight. I'm looking at oversize tubing for stiffness, because I'm heavy. I'm asking a very basic question here: Given what I've told you, should I go 725 for freak factor, or spring the extra $150 for the stiffness/trickness/strength of the 853?
Humbly thanking you in advance,
