Two CPLDs on one board & ISP

Hi, I am laying out a prototype board that will have two CPLDs on it (a MAX7128S & a 7160S). My intention is that they will be programmed "in system" using a JTAG interface. I plan on...

Any recommendations for through-hole? I'd hate to put another bunch of 74hc244/245's on there..

Why would you use through-hole? There aren't many FPGAs or CPLDs left in through-hole packaging ...

SMT soldering is pretty simple. Its very easy to solder 1206+0603 resistors, 0402 is a bit of a pain, but not impossible. IC packages like SOIC8, TSSOP16, and TQFPs with pins (no thermal land on the underside) can all easily be hand soldered. Worst-case you remove solder shorts using solder wick. Watch a few YouTube videos and you might feel encouraged to try :)
