going from 19.3tt to 20.3tt - noticeable difference?

I've been riding my Autum Razzia 19.3TT with 12.5 Chainstays off and on for the better part of 2 years. I have since picked up a LOT more street style riding while also making progress in flatland. I am looking to buy a new frame that will accommodate a 14mm axle freecoaster, but with the same or similar short chainstay length. This leaves me with a dilemma:

1) Have a custom frame made with the dropouts I'm looking for and a similar sized TT.

OR

2) Buy a street style frame with the same chainstay length. I had in mind the BSD ALVX in 20.3 TT that has 12.5 CS. This would be a full inch bigger than my current Razzia TT.

I'm terrified that I will drop the money on the BSD and end up hating the longer TT. I would like some input on this. I am running a 35mm stem and some Animal Scerbo bars with 15mm offset forks.

Another concern is the full degree of deviation in the headtube angle: from 74.5 to 75.5

have you thought of grinding / filing down the dropout slots?

Just get a modern flatland frame. Like the s&m intrikat, that comes in 19.5 with a 12.75 chainstay. Have a look at the flatlandfuel website, there's loads of frames on there that will be cheaper than a custom

Edit: I misread this slightly, but I'm sure you can find a frame that will do what you want if you look around. I'm a member of a group on Facebook, there's a guy on their with the intrikat that rides a bit of ramp and street, as well as flatland

Haven't given it any serious consideration. I don't have the equipment, nor the motivation to pay someone to grind/machine them. I'd sooner hang it on the wall than mutilate it. I guess that is to say I love the Razzia enough not to mess with it if that makes sense. Sentimental at this point

The intrikats I see have a 13" rear end. A little longer than I'd like

According to the s&m website they're 12.75. And that extra 1/4" will feel a little more stable for street

Will you notice the difference ? Yes definatly.
But this short ALVX seem to be a great option, I always thinked a short back end is far more important than a short top tube to get a responsive bike, and it's strong if you dig into street riding.
I tried a friend's alvx in 20.6" it's crazy how quick it feels, my friend is learning some great flat moves with it.
About the head tube angle, getting steeper is like going for a shorter fork offset.
