Ya know, you have all these people here telling you that a class win is inevitable (including myself), but you have been around long enough to know that it is never a guarantee with BB'ing being a subjective sport. Who knows, the judges may be after a fuller, bigger, rounder look on that particular day as opposed to a tighter, harder, dryer look. you just never know. Also, you make a good point, none of us have seen you NEXT to anybody. We can obviously tell from the pics that your conditioning is pretty much impossible to be beat, but who knows what you will look like next to a guy who is at the very top of the weight class but has the illusion of being a light heavy (hell, you create this illusion anyways lol). Sure, you will be shredded to the bone, but will the next guys illsuion of so much more size overpower this? Maybe, maybe not.
All I know is that conditioning is the first thing I look at when I am judging a phsyique for myself (no, I am not a judge). And I have got to say that I am so impressed with your conditioning that I really can not engineer a paragraph of words that would accurately describe how in "awe" or how impressed I am with your condition. That right there would make me (and probably 99% of the other gusy here) give you the nod for even an overall win. However, we are not the judges. so you jsut never know.
On the flip side, no matter what the outcome is, you can already be proud in knowing that you have reached the aboslute best condition and package that you could possibly reach at this point and it sounds like you have done everything you could possibly do to be at you VERY best. That is what you should strive for no either way...your personal best, b/c that is all you can cotnrol, as you already know. Having said all of the above, yes, I think it is VERY possible (more likely probable) that you will take your class, and with that kind of conditioning, even as being a "small" guy, I would say you would even have a good shot at the overall. but like I said above, you havne't stood next to anyone yet and you just never know what the judges are looking for.
Best of luck to you man, you have inspired me and for those who have ever gotten anywhere near contest shape (including myself) I think they can appreciate and understand the amount of effort and hard work you have put in to present what you have presented in these pics and I also think that 99.9% of them know inside themselves that they probable don't even have the mental focus and ability to get into this kind of shape (including myself).
