My experience and observation is that 555-based trems are unfixably ticky, with no real advantage.

Hey, Adriano, I have a fantastic idea: Why don't you breadboard it and tell us what it sounds like? ...Just kidding...
No experience from my part with those opamps, but thanks for the link

+1.  Even the low current kind (7555) are still noisy (audibly so).  The only way I got rid of my '555' ticking was some fairly extreme filterin on the output signal - which robbed all my guitar's 'top end'.

Better to use a dual op-amp LFO (as in the Phase 90 I think) - *much* quieter.

I had a 555 tremolo designed and breadboarded that was dead silent.  I kept it on the board for weeks and tweaked it with no ticks.  Finally, on the day I decided to build it on vero it was ticking.  I figured something must have just moved on the breadboard so I built it anyway, and now it ticks like crazy...
