I had big hopes for building a 650 from parts & a 610 as well,but I found out yesterday that I'm going on the cutting block on 9/20 for my 5th back surgery.It seems that I'm so powerful that I can break titanium screws,Lol.I've been going through hell with the pain since May 2020,but because of the pandemic it was put aside because this was considered an "elective" surgery.I beg to differ on what they consider to be an elective surgery.I'd consider a face lift,or a tummy tuck to be elective,but not broken hardware in one's back.I went through pure hell with the last back surgery 3 yrs.ago.I had to wear a wound vac for over 2 months,had an intraveinous antibiotic that I had to administer to myself twice a day,& had visiting nursers come to pull a 7 cm.sponge out of the incision as it got smaller.I almost pissed myself with the pain from that,but it got progressively better as I healed.The original surgery was on Oct.9th & I had to go back in & have it cleaned out & the wound vac installed along with a PICC line 6 weeks later.
I suppose the 650 & 610 builds can wit till next yr.
