Cackerot69-- Once one gets in to a routine the muscles adapt and it is much easier to reach a plateau. This is well know. By routine i don't mean periodzation, i mean the same progarem week and and week out.
As for front raises given cuts, for me it's has brought out the overlapping anterior delt to the bicep. It also helped shape round inner anterior delts (ones that strech acros the pectoris minor. Although on occation i do do them, i only go light, heavy reps because i find that 1 - it takes forever to make gains in my anterior delts and 2- it causes my injurieis.
That is all, don't get into a routine!!!
