I purchased the Pilot Explorer in Metallic Lime Green with a fine nib and the recommended converter and it works very nicely with Lamy black ink on Rhodia paper and also on cheap exam pad paper. The Pilot fine nib size is subjectively in between the thickness of a Platinum 02 extra fine nib and slightly thinner than a Platinum 03 fine nib and it writes quite smoothly. The pen is light enough to use capped and there is no imbalance when capped. Overall I usually do math calculations on exam pad paper with Greek letters and subscripts and superscripts and I am very happy with this purchase.
