Hi - I've been riding a PX Pro Carbon since 2012. I bought it second-hand then, the frame is 10 years old now and I want to upgrade.
I didn't pay any attention to its geometry when I bought it beyond the letters "XL," but now that I'm looking to upgrade I've realised just how Goldilocks its numbers are for me...but, even then, it's right at the lower end of how long a frame I need.
Here's my setup for reference:

The frame has a stack/reach of 590/405, the seatpost has a 20mm setback (but is set forward, with the saddle as far ahead as it'll go) and the stem is a 150. The bars are short reach with a 15mm rise.
I'd like an aero bike, but very few frames seem to let you get the saddle forward (as they all use proprietary seatposts,) but two I've found with that feature are Boardman AiR frames and Felt's AR series.
An AiR in XL/60cm has a stack/reach of 586/405, an AR in 58 is 587/405 and in 61 is 616/417. So the biggest AiR isn't big enough, but the biggest AR should be.
I would like to be able to use a stem shorter than 150mm, as I'm way out over the front wheel as it is, and my knees sometimes bang the back of the stem. If I could get the seatpost even further forward, I'd probably have it another 1/2cm ahead. The Felt has a reversible seatpost that would let me do that...does anyone know of any other frames with similar numbers? I will have to buy second-hand again, and AR frames in 61 are thin on the ground. I'm open to considering TT frames, but I'm worried they might be boat anchors, and most of their stack numbers are very low, so I'd have to use spacers, or a stem with rise...ew.
For the record, the position as-is is comfortable for 12-hour days, fast and great for climbing, and with a set of clip-ons with extensions mounted below the bars (Ambrosio Atritium 1s, in case anyone cares...) my back is flat and parallel to the ground.
Any help/advice/whatever appreciated!
