Cutnedge,
I've been playing with english for 46 yrs. & I have never shot a spot shot the way U described.(full ball) Were you hitting the cue ball on the exact horizontal axis & were you hitting with inside or outside 'english'? You may have been making the shot with deflection rather than spin. Hence bbb's question about the shafts, old regular high deflection or newer low deflection.
As to the cloth, the Simonis is slicker & faster than the old 'felts' but there also seems to be less cushion between the slate. So, there is a bit of an offset. I'm speaking in reference to english only. When I first started playing on the Simonis I was under cutting some of the outside english shots & over cutting some of the inside english shots. It's due to a bit of difference in the cue ball swerve factor & is also dependent on the speed of the shot & sometimes a skid is involved.
With a little practice you should be able to subconsciously adapt.
Just my $0.02 & please note I am not an instructor.

FYI, with nap cloth, it depends if the cloth were properly brushed or not. Properly brushed (i.e. from head of the table to the foot of the table *only*, in long swipes), you have direction in the nap of the cloth.
The technique that the OP describes actually does work, because, in a directional nap, of the way the spin "grabs" the tips of the fibers as the cue ball rolls over them. Obviously, unmaintained nap cloth has fibers going in every which direction, so carefully applied spin doesn't have the same effect as it does on directional nap.
Snooker tables use nap cloth, and the cloth is ALWAYS brushed from head to foot to create the directional nap. In fact, when you see a referee replace a colored ball back on its spot, you'll always see him/her place the ball on the table slightly "high" (i.e. above the spot), and then gently roll the ball "downwards" (with the nap of the cloth) onto its final resting place on its spot.
However, pool tables are not exactly known for the same level of meticulous maintenance and care that snooker tables are, so it's quite possible that the place(s) the OP played at, differed from yours in levels of TLC afforded to the nap cloth. Like I said, maintained nap cloth definitely *does* affect the cue ball's travel with spin (it gently masses); while unmaintained cloth doesn't.
Although this topic is well-known in the snooker circles, the best reference in the pool world that I can find about nap direction affecting the path of rolling balls, is Freddy the Beard's "Banking with the Beard" book and video. Freddy goes into good detail how the balls roll over a well-maintained nap cloth vs. unmaintained cloth.
I would highly suggest you check out "Banking with the Beard" if you've never heard of this. It will definitely open your eyes!
EDIT: I just found a video that demonstrates this effect of a properly-maintained nap cloth upon rolling (without spin) and spinning balls. Notice that in the UK, the term "side" is used to describe spin, or your "english!" RJ.
