Cut old spikes??

[Celtic100]

I recently (Feb) split and transplanted a very old cattleya into two pots. It was a real hack job as the plant had been in the same pot for too long (3 yrs) and did not want to move!! I had to take a large knife and "saw" thru the root system. It was not pretty. Anyway, I put each transplant into those "swiss cheese" pots and they seem happy, so far. One has sent up 4 new spikes and the other smaller one, 2 spikes. I would like to cut a few of the older spikes and let the new ones take off - the old spikes are unattractive to say the least. If it is not wise to do so now, would I be able to after the new spikes have developed more. Thanks
