NJ,

I have been flying the same GP Extra 300 plane for over a year. I have used the stock hardware and same wooden push rods, to this date they have not given me any problem nor any slop. Initially I was also hesitant but my senior club member advised me to go with supplied push rods. I do agressive aerobatics and these push rods are still going great. Use them without any fear it may be after couple of years that you may find slop than it will be time rethink what to do. Just my 2cents opinion, you have every right to use hardware of your own choice.

Thanks,
IK
