Not really true, the stiletto cab is a true straight cab which means more internal volume. I would say it is like the standard slant, but more of in the middle of the standard and the stiletto slanted.
I have owned both tradtional cabs (stiletto) and go on this from experience.
Now as to cab shopping, you also have to be carefull with the mesa cabs, if it is a newer cab it has the normal celestion V30's and will be rated at 240 watts. If it is a older cab it will have the specially voiced V30's that have better lows, little less mid's and will be rated at 280 watts. By the way, this has been verified by a mesa endorser who spoke to his rep. Mesa went back to the normal V30's because that is what people wanted and what the music scene was going towards.
Many stores out there still have alot of the older cabs so that is why you have to look. By what you are saying, i think a stiletto, AKA traditional cab with the older V30's would probaly suit you nice.
With that said, a straight Stilleto WILL NOT sound like a slant Recto cabinet. No way, no how. One is much bigger than the other, regardless of baffle. Recto cabs define the nu-metal sound.
