To change 729 CROSS to JOOLA XPress

Hello, that such.
2 weeks ago I use a rubber 729 Cross that now very slow this one and I do not like it so much, and a friend changes me into a secondhand Joola Xpress, 2 months that it has some faults, but it continues with his characteristics, at the time...
Do I change? Or do I continue with 729?

Never change china product.

 

i would stick for 1 more month or so then consider changing

 

GOOD idea, I just get my DHS H2, the glue stick to water, it is normal that sucks the blow?
